I'm installing a PC for my mother, she's got bad eyes and therefore likes to
have the mousetrail. But I can't get it to work. Off course I tried all the
settings in windows configuration/mouse. After that I installed logitech
mouseware, and tried other mouses. Nothing seems to work.

Anyone knows a solution?

W98SE, full updates, 2 button PS/2 mouse, 3 button wheelmouse, etc.
